Tasya [4]3 years ago

Step-by-step explanation: B

put the center of the circle on the right of the line and the edge of the circle on the p. Make part of a circle. you dont have to do the whole circle, but you can if you want.

do the same thing again but on the other side of the line.

now it should look like the first image i included (if you didnt do the whole circle)

now take your straightedge/ruler/line maker and make it go through the intersecting points on the circles, like the second image.

Note that my images are for demonstration. They're not perfect at all, they're just to show you how to do it.

Use the diagram to find the measure of arc. AB and CD and the diameters of the circle F
dybincka [34]

Answer:

11). m(\widehat{DE}) = 90°

12). m(\widehat{AEC}) = 212°  

Step-by-step explanation:

A circle F with AB and CD are the diameters has been given in the figure attached.

11). Since, m(\widehat{AB}) = 180°

    and m(\widehat{AB})=m(\widehat{AD})+m(\widehat{DE})+m(\widehat{BE})

    Therefore, m(\widehat{AD})+m(\widehat{DE})+m(\widehat{BE}) = 180°

    32° + m(\widehat{DE}) + 58° = 180°

    m(\widehat{DE}) = 180° - 90°

                = 90°

12. Since, m(\widehat{AD})=m(\widehat{BC}) = 32°

                 m(\widehat{AEC}) = m(\widehat{AB})+m(\widehat{BC})

                                = 180° + 32°

                                = 212°

What does simplify the expression mean in algebra?
Pavel [41]
Reduce the number of terms in the expression by operating on like terms 
for example
Simplify
x^2 - 3x + 4 + x^2 + 6x - 6

the like terms are the x^2 and x^2 , -3x and 6x and  4 and -6 

so we have
x^2 + x^2 - 3x + 6x + 4 - 6
= 2x^2 + 3x - 2

This is the simplified form of the original expression

70% of Ms. Miller's class passed the test on the first try. Those who failed were able to retake and half of those students pass
MrRissso [65]

Answer:

85%

Step-by-step explanation:

  1. Calculate how many students passed on their first try. 20 x 70% is 14, so 14 students passed on their first try.
  2. 6 students retook the test. Half of 6 is 3. Add 3 to the 14 students that passed earlier.
  3. Calculate the percent with the equation 17/20 = 0.85. 0.85 = 85%.
